devel/boost-libs fails to build its test suite on non-x86, due to not including osreldate.h, in the execution_monitor. A fix was applied to the trunk, but never merged into the release branches.
Fix: Patch attached with submission follows:

The original trac ticket and fix can be found at:
https://svn.boost.org/trac/boost/ticket/3897
The patch is only in trunk, it's not in the release branch. If trunk
ever does branch again, it will be included in likely a later major
release (boost2, maybe?).
